What is Vardenafil?

Vardenafil is a potent, selective PDE5 inhibitor with higher PDE5 affinity and greater selectivity over PDE6 than sildenafil, providing potentially fewer visual side effects. Studied for PDE5 pharmacology, erectile physiology, cGMP pathway research, and comparative PDE5 inhibitor pharmacology. Research use only.

Research Applications

PDE5 Inhibition Pharmacology

High-affinity PDE5 inhibition — IC50, selectivity profile, cGMP elevation

Comparative PDE5 Research

Vardenafil vs sildenafil vs tadalafil — selectivity, potency, PDE6 cross-reactivity

Erectile Physiology

Corpus cavernosum smooth muscle cGMP, NO pathway amplification

PDE6 Selectivity Research

Retinal PDE6 selectivity — visual side effect mechanism vs sildenafil comparison

Cardiovascular cGMP

Vascular smooth muscle relaxation, pulmonary hypertension, endothelial function
